China cold galvanized steel pipe

Many people should be heard galvanized steel pipe and understand the application of the steel tube. However, a few people know more details of the differences between pipes. As a result, more people will be cheated by steel pipe suppliers. So what do you know about galvanized steel pipes? The differences and application of galvanized steel pipes are the two main aspects. There are two kinds of different specifications according to the pipe shape. That is round steel pipe and square steel pipe. The difference between these two kinds of pipes is quite obvious. Moreover, pipe price is different but not obvious. The price of round steel pipe is lower than that of the square steel pipe because square steel tube in the consumption of materials will be higher than that of round steel pipe. Therefore, the cost price is relatively high and retail selling price will be increased correspondingly.

Another classification standard is galvanizing method which is divided into two kinds: hot galvanizing and cold galvanizing that can form cold galvanized steel pipe. How to produce hot dipped galvanized steel pipe? It should be immersed into zinc solution. After cooling, it will form a layer of zinc coating that is very thick on the pipe surface. So there will be a very effective insulation effect. What about cold galvanized steel pipe? Cold galvanizing is to spray a layer of zinc solution on the surface of the ordinary steel tube such as welded square steel pipe. This galvanizing method will lead to thinner coating and the insulating effect will be worse.

At present, the most important specification of the galvanized steel tube is hot galvanizing and cold galvanizing. It is quite difficulty distinguishing these two kinds of steel pipes. How to identifying them? In general, the zinc layer of hot-dip galvanized steel tube is thicker and the color is also darker while the cold galvanized steel pipes take the opposite side. Of course, the insulating effect of hot galvanizing is much better than cold galvanizing. Hot galvanizing will be more suitable for some insulation requirements than cold galvanizing and the industries related to the power industry are more suitable for hot galvanized steel pipes. Cold galvanizing steel pipes can be applied to some ordinary insulation occasions. If you want to purchase cold galvanized steel pipe , the steel pipe price is much lower which can be helpful to your project budget.
